Concrete Padstone 330mm x 215mm x 102mm – PAD13
The Concrete Padstone 330mm x 215mm x 102mm, also known as PAD13, is a high-strength precast concrete unit used to create a strong and stable bearing beneath structural beams and lintels. It helps distribute concentrated loads across the supporting brickwork or blockwork, reducing the pressure placed on a small area of masonry.
Padstones are commonly required where a steel beam, concrete lintel or another structural element rests on a masonry wall. The dense concrete construction provides a stronger bearing than an ordinary brick or standard building block, helping transfer the imposed load more effectively into the surrounding structure.
The PAD13 format measures 330mm long, 215mm wide and 102mm high. Its compact proportions make it suitable for structural details where a 215mm-wide bearing is required but the longer dimensions of PAD12 or PAD09 are not necessary.
What is a concrete padstone used for?
Structural beams carry loads from elements such as floors, roofs and walls. These loads are transferred through the ends of the beam into the masonry below.
If a beam is supported directly on unsuitable masonry, its load may be concentrated into an area that is too small or too weak. This could cause excessive stress, cracking or crushing within the supporting brickwork or blockwork.
A correctly specified padstone provides a high-strength intermediate bearing. It spreads the concentrated load over a greater area and helps transfer it into the supporting wall.
Typical applications include:
- Supporting structural steel beams
- Providing bearings beneath steel or concrete lintels
- Forming new structural openings
- Load-bearing wall alterations
- Residential extensions
- Renovation and refurbishment projects
- New-build houses
- Commercial masonry construction
PAD13 dimensions
The nominal product dimensions are:
- Length: 330mm
- Width: 215mm
- Height: 102mm
- Product reference: PAD13
- Approximate imperial size: 13″ x 9″ x 4″
- Material: High-strength precast concrete
The 330mm length provides a substantial bearing area while remaining more compact than a 440mm or 600mm padstone. Its 215mm width is compatible with certain solid-wall and masonry arrangements, while the 102mm height creates a lower-profile structural bearing.
The product’s dimensions alone do not determine whether it is suitable for a particular project. The correct padstone must be established through structural calculations and the approved construction design.
Benefits of precast manufacture
PAD13 is manufactured under controlled factory conditions and supplied ready to install. This avoids the need to create shuttering, mix concrete and cast a structural bearing on site.
An in-situ padstone must be properly formed and allowed to cure before it can safely accept a structural load. Using a precast unit can reduce on-site preparation and waiting time while providing more consistent material properties and dimensions.
Benefits include:
- Ready-made structural bearing
- Consistent factory production
- No on-site concrete casting required
- No separate shuttering or formwork needed
- Reduced installation time
- High-strength concrete construction
- Defined dimensions for straightforward specification
- Suitable for new and existing masonry
The bedding mortar and surrounding masonry must still be allowed to develop sufficient strength before the padstone receives its full structural load.
Selecting the correct padstone
Padstone selection is an important part of structural design. The required size depends on the beam reaction, end-bearing length, masonry strength, wall construction and the loads carried by the beam.
PAD13 should only be used where the 330mm x 215mm x 102mm size has been specified or approved by a qualified structural engineer or another suitably competent professional.
A padstone should not be selected solely by comparing its width with the beam or wall. It should also not be substituted for another padstone size without approval, even if the alternative product appears larger.
Check the structural drawings and calculations before ordering. These should confirm the padstone dimensions, orientation, position and required bearing arrangement.
Installation guidance
The supporting brickwork or blockwork must be sound, stable and capable of carrying the transferred structural load. Install the padstone on a continuous bed of suitable mortar, ensuring it is level and fully supported.
Position the unit in the orientation shown on the structural drawings. The beam or lintel must have the specified bearing length and should be correctly seated on the padstone.
Inspect the product before installation. Do not use a severely cracked or damaged padstone if its structural performance may have been affected.
Padstones should not be cut, drilled or otherwise modified unless the alteration has been expressly approved by the structural engineer. Allow the mortar and supporting masonry to achieve adequate strength before applying the full load.
Colour, finish and size variations
Precast concrete is made using cement and naturally sourced aggregates. Differences in raw materials, production conditions and curing can result in minor variations between individual products.
Please note: Colours and sizes may vary slightly due to the manufacturing process. Product photographs are representative and the item supplied may differ slightly in appearance.
Small air pockets, surface marks, shade differences and minor edge variations are normal characteristics of precast concrete. These cosmetic differences do not necessarily indicate a product fault, provided the padstone remains structurally sound and within the manufacturer’s permitted tolerances.
As padstones are functional structural products rather than decorative units, exact colour matching cannot be guaranteed.
